Page 13
Microwaves
The radio in the Dolphin RF terminal operates on the same frequency band as a
microwave oven. Therefore, if you use a microwave within range of the Dolphin RF
terminal you may notice performance degradation in your wireless network. However,
both your microwave and your wireless network will continue to function.
The Dolphin Batch terminal does not contain a radio, and therefore, is not affected by
microwave ovens.
Batteries
•
Use only the battery supplied with your Dolphin or a replacement battery
supplied, recommended, or approved by Hand Held Products, Inc.
• Replace a defective battery immediately as it could damage the Dolphin
terminal.
• Never throw a used battery in the trash. It contains heavy metals and should
be recycled according to local guidelines.
• Don’t short-circuit a battery or throw it into a fire. It can explode and cause
severe personal injury.
• Excessive discharge damages a battery. Recharge the battery when your
Dolphin indicates low battery power.
• Although your battery can be recharged many times, it will eventually be
depleted. Replace it after the recommended usage period (about 500 charge
cycles for the 1500 mAh NiMH battery) or if the battery does not hold a
charge.
• If you are not sure the battery or charger is working properly, please send it to
Hand Hand Products or an authorized Hand Held Products service center, for

CHAPTER 1 GETTING STARTED
3 Turning the Dolphin On And Off
Turning On the Dolphin
1. Install the charged battery pack in the Dolphin.
2. Hold the Dolphin in the palm of your hand so that you can press the ON/SCAN
key easily with your thumb.
3. Press the ON/SCAN key to turn the Dolphin on. Your Dolphin will boot up just
like a desktop PC and the title screen for the HHP Demo Application will appear
on the display.
If the title screen does not appear on the display of your Dolphin, the HHP Demo
Application has been removed from your terminal. Therefore, you will see a DOS
prompt on the screen. Example: C:\ or A:\ .
Note: If using the Dolphin for first time or if the terminal has been without a battery pack for more
than 30 minutes and you are now inserting a battery, you may receive a CMOS error when the
terminal boots up. Don’t worry, the terminal is OK. This simply means that the internal back-up
battery needs to be recharged and the date and time need to be reset. To recharge the internal backup
battery and reset the date and time, insert a fully charged battery in the Dolphin and then use the DOS
date and time function to set the correct date and time. The internal back-up battery requires a
minimum of 5 hours of charging time in order to perform and maintain the system as described on page
30.
Turning the Dolphin Off
The Dolphin is never actually turned off. To conserve power, the Dolphin goes into
“sleep mode” when it is inactive for a programmed period of time as defined by your
application. The screen is blank when the Dolphin is in “sleep mode.”
4 Setting the Date and Time
Use the DOS date and time function to set the correct date and time for your Dolphin
terminal.
To set the date on an alphanumeric Dolphin:
1. Enter <DATE> at the Dolphin’s DOS prompt.
2. Press NUM LOCK to put the Dolphin in numeric mode.
3. Enter the new date <mm-dd-yy>.
4. Press <ENTER>.

CHAPTER 2 DOLPHIN BASICS
Maintaining the Dolphin’s Batteries
CAUTION: Use only the 3.6V battery packs provided by Hand Held Products.
The use of any other battery pack in the Dolphin 7200 terminal will void your
warranty and may result in damage to the Dolphin terminal or battery.
There are two batteries in the Dolphin:
Internal NiMH Backup Battery
Located inside the Dolphin, this battery backs up the RAM and clock when the NiMH
main battery is discharged or removed from the terminal.
NiMH Battery Pack
The battery pack is the primary power source for operating the Dolphin.
Internal NiMH Backup Battery
The Dolphin’s internal backup battery prevents the terminal from being reset if you
need to remove and replace the main battery pack. The battery retains RAM data and
allows the real-time clock to remain operational for up to 30 minutes when the battery
pack is removed. If the internal back-up battery becomes discharged of power, it
requires a minimum of 5 hours of charging time in order to perform and maintain the
system as described above.
NOTE
Return the Dolphin to
an authorized service
center when the
internal battery needs
to be replaced.
The internal backup battery is charged by the Dolphin’s main battery pack. If the
terminal is left without the main battery pack for more than 30 minutes, the internal
backup battery needs to be recharged.
Note: Data and programs on Drives C and D remain safe even if the internal backup battery fails.
However, you must reset the real-time clock using the DOS Time and Date function.
Follow these guidelines to maximize the life of the Dolphin’s backup battery:
• Keep a charged NiMH battery pack in the Dolphin. The internal battery
will prematurely discharge if there is not at least a partially charged battery
in the terminal.
• Put the Dolphin in the HomeBase when the terminal is not in use.
33
333333
Page 34
NOTE
Keep a charged
battery pack in the
Dolphin at all times to
conserve the internal
back-up battery.
NOTE
For maximum battery
life, Hand Held
Products recommends
that you deep-cycle
(service) the battery
twice
before initial use
and then, once a month
thereafter.
CHAPTER 2 DOLPHIN BASICS
NiMH Battery Pack
The 3.6V, 1500 mAh Nickel-Metal-Hydride (NiMH) battery pack is the
primary power source for the Dolphin. Other Nickel-Metal-Hydride
batteries may be approved by Hand Held Products, Inc. to work with your
Dolphin. Contact Hand Held for more information.
The 1500 mAh NiMH battery is designed to operate in temperature range
of –10 to 50 °C (14 to 122° F). For maximum performance, charge the batteries
between 10 and 35 °C (50 and 95° F).
Performance specifications for a fully charged 1500 mAh NiMH battery:
Up to 20 hours of usage in a Dolphin Batch terminal with a full battery charge
Up to 10 hours of usage in a Dolphin RF terminal with a full battery charge
Keep a charged battery pack in the Dolphin at all times to conserve the internal backup battery. When you remove a battery pack, insert another battery pack in the
Dolphin. The internal battery will prematurely discharge if there is not at least a
partially charged battery in the terminal.
Servicing the Battery Pack
For maximum battery life, Hand Held Products recommends that you deep cycle the
battery twice before initial use. It is also recommended that you service, or calibrate
the battery once per month. To deep cycle, insert the battery into the HomeBase
auxiliary battery well. Then, push and hold the Service Aux Batt button for at least 4
seconds.
For more information, see the section on the Service Aux Batt feature of the HomeBase
in Chapter 7.
Charging the Battery Pack
You can recharge an individual battery pack using the auxiliary battery well of the
Dolphin HomeBase or the Dolphin 10-Slot Multiple Battery Charger. Both accessories
use a charging method that senses when the battery pack is fully
charged and then drops to a trickle charge to keep the battery
pack at full capacity.
For more details, see the section on Charging Batteries in the
HomeBase in Chapter 7.
34

CHAPTER 2 DOLPHIN BASICS
Storing Batteries
To maintain top performance from batteries, follow the guidelines below when storing
them:
• Avoid storing batteries outside of the specified range of -4 to 104° F
(-20 to 40°C) or in extremely high humidity.
• For prolonged storage, do not keep batteries stored in the terminal.
• During long-term storage, battery deactivation may tend to occur which
may cause charging to stop early during recharging after storage. This
issue can be handled by charging and discharging the battery several
times. Also, the first charging after prolonged storage may yield a lower
than normal capacity. While this will vary depending on the storage
conditions, charging and discharging the battery several times will
almost completely restore capacity.

About the Dolphin 7200 RF Handheld Computer
The Dolphin 7200 RF® terminal integrates the basic functionality of the Batch terminal
with an 802.11b or a WLIF™ interface that allows the terminal to communicate with a
host computer via a wireless local area network (WLAN). Both radio options operate
in the 2.4 GHz frequency band. Terminal emulation software and keypad overlays for
IBM 3270, IBM 5250 and DEC VT100/220 emulation are available for both radio
options. The terminal’s DOS compatible 386 microprocessor is easy to program and
developers can create wireless applications linked to a host PC, using RF Simplicity®
and MS Visual Basic™.
Refer to Chapters 1 and 2 in this manual for more on basic operation of the Dolphin
terminal and accessories available.
802.11b-Compliant Dolphin 7200 RF Terminal
The 802.11b-compliant Dolphin 7200 RF incorporates a Cisco® 802.11b Micro-ISA
radio. The radio uses direct sequence spread spectrum (DSSS) technology, which
spreads its signal continuously over a wide frequency band, and provides an Ethernetlike data rate of up to 11 megabits per second. The radio may also provide up to 128bit Wired Equivalent Privacy (WEP) encryption. WEP is used to encrypt and decrypt
data signals transmitted between Wireless LAN (WLAN) devices. It is an optional
security encryption mechanism defined within the 802.11 standard that makes a
wireless LAN link as secure as a traditional wired link. The optional WEP security
mechanism is available with 128-bit or 40-bit encryption.
Dolphin 7200 RF is interoperable with other 802.11b-compliant products to

CHAPTER 3 DOLPHIN 7200 RF HANDHELD COMPUTER
Setting WEP Modes And Keys On The 802.11b Radio Card
This section describes how to set WEP (Wired Equivalent Privacy) modes and keys on
the Cisco® 802.11b radio card.
WEP is used to encrypt and decrypt data signals transmitted between Wireless LAN
(WLAN) devices. WEP is an optional IEEE 802.11 feature used to provide data
confidentiality that is equivalent to the confidentiality of a wired LAN that does not
employ crypto techniques to enhance privacy. WEP makes a wireless LAN link as
secure as a wired link.
The wep.bat utility is used to set WEP modes and keys for the Cisco® 802.11b radio
card. The wep.bat file uses three files:
wepdos.exe – an executable file that configures WEP values for the Cisco radio
keys.exe – an executable file that calls the functions for setting WEP values
cscpkt.ini – a configuration file for the Cisco radio
All four files are located in the Dolphin c:\rf directory that is part of the
stackcsc.exe file.
If the user will be setting WEP keys using the batch mode, the user must create a
keys.txt file using a text editor such as Notepad and then copy it to the c:\rf directory.
This file will contain the encryption keys used when operating in WEP mode. For
obvious security reasons, this file will be automatically deleted upon running the
wep.bat utility. HHP recommends that you verify that the keys.txt file has been
deleted.
Refer to the Cisco documentation for complete descriptions of the various WEP
modes. The current radio card may not support some modes.

HANDHELD COMPUTER
About Dolphin 7200 with Image-Capture™
Handheld Computer
The Dolphin 7200 Image-Capture handheld computer incorporates a low-power,
high-resolution camera to electronically capture and store images such as signatures,
airbills, and damaged cartons. The terminal can also be used to also scan barcodes
when equipped with a laser scanner.
A CMOS (complementary metal oxide semiconductor) camera is mounted inside the
Dolphin terminal next to the laser scanner making the ergonomics of using the camera
similar to using the scanner.
The Dolphin Image-Capture handheld computer can easily hold a minimum of 100
signatures with the Dolphin’s standard memory configuration of 2 MB RAM and 2
MB non-volatile FLASH memory. Images can be compressed and stored using
industry-standard data compression technologies. The device provides the flexibility to
store either images that contain grayscale information or black and white only
information. Images can be downloaded via HomeBase™ or VehicleBase™
communication cradles and then transmitted via one of many wired or wireless
options.
The device is equipped to capture images in total darkness with its own lighting source.
The CMOS camera is a function and feature extension of the Dolphin platform. Like
the batch version, Dolphin Image-Capture can be equipped with up to 10 MB of flash
memory for data and application storage. Dolphin Image-Capture handheld computer
also supports all scan engine versions available for the Dolphin platform. Refer to
Chapters 1 and 2 in this manual for more on basic operation of the Dolphin terminal
and accessories available.
Capturing Images
The image-capture process is a split-second operation for experienced users. By
following the basic guidelines, new users can easily develop their own technique and,
with practice, quickly learn to adapt it to different circumstances. The basic steps for
acquiring images using the Dolphin Image-Capture terminal are:
1. To aim, hold the Dolphin terminal horizontally at a 90° angle approximately 3 to
12 inches away from the target. You may have to adjust the angle at which you
hold the Dolphin if there is glare on the screen.
63
636363
Page 64
CHAPTER 5 DOLPHIN 7200 WITH IMAGE-CAPTURE
HANDHELD COMPUTER
2. Press the ON/SCAN button to take an image. Use the live video image on the
terminal screen as a guide for positioning and aiming the terminal at the target.
You may find it helpful to start by moving the terminal further away and then in
closer to the target. The active screen image will have a slightly degraded
appearance compared to the captured image. This is normal.
3. Release the ON/SCAN button to capture the image when the desired image is
displayed on the terminal screen. Hold the Dolphin terminal as still as possible
when capturing the image.
The image quality and related file size is determined by the data compression method
used by your software application. For highest quality, take grayscale images. When
saved, the image will be saved in JPEG file format. The size of the file depends on the
information content of the image and will be approximately 5-10K.
Grayscale Image
Images may also be saved in a file type that contains black and white information only.
The file is saved in GIF file format and will be (approximately 1.5 to 2K).

About the Dolphin 7200 2D Hand Held Computer
The Dolphin™ 7200 2D handheld computer features the IMAGETEAM ™ 4250
Image Engine, a low power, high-resolution digital image engine for omni-directional
and auto-discrimination reading and decoding of linear barcodes, stacked linear
(PDF417) and 2D matrix codes. The image engine functions like a digital camera and
also provides OCR (Optical Character Recognition) functionality.
The terminal is available in several configurations with alpha/numeric and numeric
keyboard options. These configurations include the standard range image engine with
2MB RAM and 2MB non-volatile FLASH memory or 2MB RAM and 8MB nonvolatile FLASH memory. A high-density image engine with the same memory options
is also available integrated into the terminal.
Like the Dolphin 7200 with Image Capture terminal, the 2D terminal also has image
lift capabilities for signature capture and proof of delivery applications. Images taken
with the unit can be compressed and stored using industry-standard data compression
technologies. The device provides the flexibility to store either images that contain
grayscale information or black and white only information. Images can be downloaded
via HomeBase™ or VehicleBase™ communication cradles and then transmitted via
one of many wired or wireless options.
The terminal is also able to decode barcode symbologies and capture images in dim
lighting conditions or complete darkness.

simplify operation and training and increase productivity. To read a bar code:
1. Press the ON/SCAN button to project the scanner’s bright red aiming beam
2. Center the aiming beam over the barcode. The red SCAN LED illuminates
when the user presses the ON/KEY key and the green DECODE LED
illuminates when a bar code is successfully decoded. The aiming beam can
be positioned in any direction for a good read.
Linear bar code 2D Matrix symbol
The aiming beam is smaller when the terminal is held closer to the code and larger
when it is farther from the code. Symbologies with smaller bars or elements (mil size)
should be read closer to the unit. Symbologies with larger bars or elements (mil size)
should be read farther from the unit.

Capturing Images
The image-capture process is a split-second operation for experienced users. By
following the basic guidelines, new users can easily develop their own technique and,
with practice, quickly learn to adapt it to different circumstances. The basic steps for
acquiring images using the Dolphin 7200 2D terminal are:
1. To aim, hold the Dolphin terminal horizontally at a 45° angle approximately 2 to 9
inches (5 to 20 cm) away from the target. You may have to adjust the angle at
which you hold the Dolphin if there is glare on the screen.
2. Press the ON/SCAN button to take an image. Use the live video image on the
terminal screen as a guide for positioning and aiming the terminal at the target.
You may find it helpful to start by moving the terminal further away and then in
closer to the target. The active screen image will have a slightly degraded
appearance compared to the captured image. This is normal.
3. Release the ON/SCAN button to capture the image when the desired image is
displayed on the terminal screen. Hold the Dolphin terminal as still as possible
when capturing the image.
The image quality and related file size is determined by the data compression method
used by your software application. For highest quality, take grayscale images. When
saved, the image will be saved in JPEG file format. The size of the file depends on the
information content of the image and will be approximately 4-8 K.
Lighting Conditions
The Dolphin 7200 2D terminal is designed to read bar codes and take images in dim
light conditions. It is suggested that you turn on the unit’s electroluminescent display
backlight when taking images in extreme low light conditions to help with aiming.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE
Hub of the System
As the hub of your Dolphin system, the Dolphin 7200 HomeBase performs three
important functions – battery management, communications and storage.
Battery Management
The Dolphin 7200 HomeBase uses a charging method that senses when the battery
pack is fully charged and then drops to a trickle charge to keep the battery pack at full
capacity. The battery pack does not need to be discharged before recharging because
this method protects the battery from damage caused by overcharging.
IrDA Optical Communications
The IR communications port on the HomeBase connects with the IrDA port on the
Dolphin. Reliable data communications at speeds of up to 115 baud can be
transmitted by the HomeBase. With no pins or contacts to break, IrDA will work
reliably for years.
The Dolphin 7200 HomeBase can be networked together for mass programming and
charging. Units are individually addressable, allowing each HomeBase to be
automatically loaded with the right information and files for its user.
Convenient Storage
The Dolphin 7200 HomeBase is a safe and convenient storage receptacle for the
Dolphin terminal. The HomeBase also holds a spare charged battery pack.

CHAPTER 7 USING THE DOLPHIN 7200 HOMEBASE
Charging Batteries In The Dolphin 7200 HomeBase
CAUTION: Use only the 3.6V battery packs provided by Hand Held Products.
The use of any other battery pack in the Dolphin Terminal will void your
warranty and may result in damage to the Dolphin Terminal or battery.
NOTE
For maximum battery life,
Hand Held Products
recommends that you deep-
cycle (service) the battery
twice
before initial use
and then, once a month
thereafter.
With the Dolphin HomeBase, you can charge a Dolphin terminal and a spare NiMH
battery pack simultaneously. The HomeBase charges the terminal and the spare battery
pack independently.
When you insert a battery into the Dolphin HomeBase, it charges the battery at the
highest rate possible. The HomeBase uses a charging method that senses when the
battery pack is fully charged and then drops to a trickle charge to keep the battery pack
at full capacity. You do not need to discharge the battery pack before recharging
because this method protects the battery from damage caused by overcharging. A
dead battery will charge to full capacity in approximately three hours.
The Dolphin Terminal can be stored indefinitely in the HomeBase without damage to
the terminal, battery packs, or the HomeBase. Keep the HomeBase plugged in so that
the Dolphin Terminal’s battery pack stays fully charged.
Charging A Dolphin Terminal
1. Insert a battery pack into the Dolphin Terminal.
2. Place the terminal, laser engine window up and the LCD visible, in the Dolphin
Terminal Well of the Dolphin HomeBase.
3. Let it glide down into the well until it stops.
4. Once the Dolphin Terminal is properly seated, the Charging Main Batt LED on
the HomeBase will be solid GREEN.

Setting Up For Communications
The Dolphin Terminal and Dolphin HomeBase support RS-232 communications
through the RS-232 Main Communications Port located on the side of the Dolphin
7200 HomeBase. The HomeBase translates the RS-232 signals from the host
computer into infrared signals to communicate with the Dolphin Terminal.
The HomeBase RS-232 interface allows the Dolphin Terminal to communicate to a
personal computer, modem, or any standard RS-232 device using a standard serial
cable and communications software.
Follow these steps to set up the Dolphin HomeBase and Dolphin Terminal for
communications:
1. Set up the Dolphin HomeBase.
2. Set-up the Dolphin Terminal.
3. Follow the data transfer sequence as described by your application.
Setting up the Dolphin HomeBase
Set the Dolphin HomeBase on any dry, stable surface such as a desktop. Before
mounting the Dolphin HomeBase, check to ensure that all AC wall transformers have
a nearby electrical outlet. Be sure to provide enough workspace with good lighting for
the user to view and operate the Dolphin Terminal while it is in the HomeBase.
Setting up the HomeBase involves three steps:
1. Connecting the cables
2. Setting the configuration switches
3. Setting the baud rate
Connecting the Cables
Connect the HomeBase to the host computer or other device by plugging an RS-232
serial cable into the RS-232 Communications Port on the rear of the HomeBase. The
